The total students
Solution :
Let the total students in the grade be as y
[tex]\bigstar \:\boxed{\sf{30\% \: of \: y = 63}}[/tex]
[tex]\sf{\implies} \: \dfrac{30}{100} \times y = 63 \\ \\ \sf{\implies} \: \frac{30y}{100} = 63 \\ \\ \sf{\implies} \: 30y = 63 \times 100 \\ \\ \sf{\implies} \: 30y = 6300 \\ \\ \sf{\implies} \: y = \dfrac{6300}{30} \\ \\ \sf{\implies} \: y = 210[/tex]
Total Students = 210
[tex]\therefore[/tex] The total students in the grade is 210.
